CNC cutting tool can be divided into two major categories of conventional tool and modular tool. Modular tool is the development direction. The main advantage of the development of modular tool: reducing tool change downtime, improve production and processing time; accelerate tool change and installation time, improve the economy of small batch production; improve the degree of standardization and rationalization of the tool; improve management and flexible processing tool level; expand the utilization of the tool, give full play to the performance of the CNC cutting tool; effectively eliminate work interruptions tool measuring and presetting can be used outside the line. In fact, due to the modules of the development of the tool, the CNC tool has formed three systems, turning tool system, the system of drilling tools and boring and milling cutter system.
CNC Cutting Tool Cutting Process Classification
CNC cutter, from the cutting process, can be divided into the following: the turning tool is exceptionally round bore, outer threaded inserts, internal threading insert, grooving, hirth ring groove, cut off. CNC lathe machine generally uses standard folder indexable cutting tools. The machine folder indexable cutter blade and cutter body has a standard blade material with carbide coated cemented carbide and high speed steel. CNC lathe machine folder can transfer the bit tool type cylindrical tool, external thread tool, the inner circle tool, internal thread tool, cutting tool hole processing tool (including the center hole drills, boring tools, taps, etc.). Machine clip indexable tool clamping throwaway films are usually screws, screw the pressure plate, bar pin or wedge structure.
CNC Cutting Tool Characteristics
In order to achieve efficient and more able, quick-change, the purpose of the economy, compared with the CNC machining tool and metal cutting tools should have the following characteristics: blade and knife handle highly universal, standardized serialization. The durability of the blade or and economic life indicators of the cutter. The standardization and typification of the tool or blade’s geometric parameters and cutting parameters, the blade or tool material and cutting parameters and the material being processed should match with each other. The tool should have a high accuracy, including the accuracy of the shape of the tool, the accuracy of the relative position of the blade and shank of the machine tool spindle, blade and hilt translocation and disassembly repeat accuracy. Shank strength, rigidity and wear resistance is better. Installed weight of the tool holder or tool system is limited. The position and orientation of the blade and shank cut have certain requirements. The blade, hilt locating datum and automatic tool change system should be optimized.
